dairy ladder
A sexual act by which a gentleman titty-f***’s a large breasted woman who is lactating while her breasts are full. The leaking milk is the only lubricant used. The gentleman makes aggressive cow noises while the woman spanks and scolds him with phrases such as “You filthy cunt!!” and “Down Bessie!”
Dude, I totally climbed the Dairy Ladder with Tiffany last night.
